    plugins/flatpak: order before icons plugin so icons are loaded
    
    Because we re-use code from the appstream plugin, locally-installed Flatpaks which are loaded from the 
local AppStream file don't get their pixbuf loaded unless the icons plugin is run after Flatpak, which means 
they are considered invalid and not shown in the Installed tab.
